NTERCHANGEABLE DE'MOU'NTABLE RTM.

Application filed March 24, 1922.

To a7? whom it may (2o/noem.'

Be it known that l, GEORGE Srninonimnn, a citizen of the. United States, residing at tlanta` in the county of vFulton and State of Georgia. have invented certain new and useful mprovements in -nterchal'lgeable Demountable RimsA` of which the following is specification.

The present invention relates to a demountable rim which embodies novel features of construction whereby it can be used interchangeably upon a number of different types of fellv constructions or fittings, thereby avoiding the necessity of having a special type of rim for each of the different felly constructions and fittings.

At the present time there is a large nunr ber of different constructions of demount able rim receiving wheels upon the market and in general use, although a special type of rim is necessary for use in connection with eac-h of the different wheel constructions. The accessory jobber and dealer is thus confronted with the necessity of carrying at all times an immense stock of all of the different sizes of eachV of the various types of rims, in order to supply individual motorists with the proper sizes and types of rims adapted to fit the wheels upon their particular vehicles. A large amount of capital is tied up at all times in this large stock of rims. and among the objects of this invention is to overcome this diihculty by the provision of a specially constructed rim which -is adapted to be used interchangeably upon a number of different wheel constructions. This lifts a heavy burden from the shoulders of the accessory dealer, and at the same time a rim is supplied to the motoring public which has a strong and durable construction`r 'and is not liable. to become warped or-bent out of shape.

ith the above and other objects in view, the invention consists in a certain peculiar construction of the rim. as will more fully appear as the description proceeds, the novel features thereof being pointed out in the appended claims.

For a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which:

Figure l is a transverse sectional 'view through a wheel felly of that type which Serial No. 546,479.

'like reference characters.

Referring to the drawings, which show the improved rim as mounted upon two diffen ent and distinct types of wheels,V the rim itself is indicated as a unit by the letter A. The rim is provided with the usual base 1 and side flanges 2, and may have the proper shape and cross section to receive any standard or conventional form of tire. The telly engaging side of the base l is provided at opposite sides thereof with the annular enlargements or ribs 3 and a, respectively, said ribs having the outer faces thereof suitably beveled or inclined. as indicated at 3 and il, and the rib 3 also having an inwardly 'facing beveled portion 3b. A third annular rib 5 is arranged between the two ribs 3 and 4, being preferably located at a oint adjacent to the rib l and being forme with anv outwardlyjinclined beveled face da. The three inwardly projecting peripheral ribs 4 and 5 serve to reinforce and stiden the rim, so that it has a rigid construction and is not liableto be warped or distorted out of shape.

ln Figure 1 of the drawings the rim is shown as applied to a. wheel formed with a wooden felly 6 surrounded by a felly band 7, said fellyband having an outstanding beveled rib 78 at'one edge thereof and corresqondingly beveled face T at the opposite er ge thereof. The rim A is slipped over the wheel from that side thereof which is provided with the beveled edge Tb. with the result. that the rib 3 of the rim engages the rib T of the felly band. The removable wedge ring may then be inserted in position with the inclined faces thereof engaging the beveled edge 7b of the felly band 7 and the inclined face 5a of the rib 5. respectively. The wedge ring 8 is held in position by means of locking lugs 9 applied to lug bolts 10 which are applied to the felly at intervals and eX- tending transversely throughthe same. Nuts 'l1 are threaded upon the projecting ends of the lug bolts 10 and engage the locking lugs to force them into operative position. The adjacent face of the telly 6 is shown as provided with a plate 12 against which the inner ends of the locking lugs 9 bear. The elly and mountings thereon are all of a, Well known construction and no claim to novelty is based thereon7 although this construction of Wheel ordinarily requires a special type of rim. It will be obvious, however, that the present rim can be applied interchangeabl to this and other`types of Wheels.

n Figure 2 of the drawings the rim is shown as applied to a Wheel which is provided with an all metal telly 13, said :telly having a channel shaped cross section and the sides thereof being provided at their outer edges with the correspondingly beveled bearing faces 13a. ln order to apply the rim to this telly it is reversed so that the interior rib 4 thereof is the lirst to slip over the elly. The beveled face 4a of this rib 4 engages one of the seats 13a of the telly, While the beveled face 3b of the rib 3 engages the other seat 13a of the telly. rlhe outer edge of the rim is then engaged by locking lu s 14 which are applied to the lug bolts 15 an forced tightly in position by the nuts 16. rllhe inner ends oi' the locking lugs 14: may engage shoulders 1T which are conveniently formed by cutting out ears from the base of the :telly and pressing them inwardly, as indicated on the drawing. rThe felly and locking means are themselves of a Well knovvn and conventional construction so that no claim to novelty is based thereon. This torni of Wheel telly', however, ordinarily requires a special -torni of rim, althorgh the present rim can be applied with equal facility to this and also 'to other types of wheels` as has been sct forth. The use of this improved rim construction Will enable the accessory jobber and dealer to supply all of the reasonable demands of the trade While carrying only a fraction or the stock of rims `which is necessary `Where each type of rim will only tit one particular type of wheel. rl`he rib 3 or the rim is preferably slightly higher than the ribs Il and 5 which are located at. the opposite side of the rire. and the arfang ent and formation ot these ribs is sucn as to specifically' admit engagement or certain beveled faces thereoi 'with the corresponding; seats or' the dililerent Wheel tellies np-oi which the. rini e iy be placed.

From the Jforegoinpj, tht at ntanes of this interchangeable rim construeren r illbe apparent but it is preferable to1 note t i by vir; tue or the arrangi and construction or the three ribs. so ated 3, 4 and 5. the rim mai of rim or telly 'hich constrncti the rib'eA acts a for the loci:- ing ring. in this position Leanser moved from the Wheel as a unit. Such In arrangement is extremely advantageous as compared with the operation of applying corresponding parts in the conventlonal form of Wheel constructions where the lookin ring does not cooperate with the rim in suc a manner as to be applied with the rim as above described. On the other hand, the use of this same rim with those types of wheels not requiring the locking-ring necessitates for its application merely the reversal ot the rim from that above mentioned. which reversal brings the proper bearine faces into coacting relation to the bearing lgaces of the felly. has a dual function in the various applications ot my special form of rim construction.

lt will be understood that the rim may be applied to other forms and. types of Wheels and fellies and that itis not restricted to use upon the tvvo particular types of Wheels which have been selected for illustrative purposes. One embodiment of the invention has been described and illustrated in detail in order to give a clear understanding of the inventive idea, although it will be obvious that numerous modidcations and changes are possible in the details of construction vvithout departing from the spirit of the invention.

Having thus described my invention what l claim as new and desire to secure by Letters Patent is,

1. demonntable rim provided upon its inner periphery With a plurality of annular ribs, each oic the ribs being formed with a beveled bearing surface and one of the ribs being formed with an additional reversely inclined hearing" surface., the rib With the two bearing surfaces being` oil a. greater height. than the other ribs, and different selected combinations or the bearing;1 surfaces being adapted to be. used in seating the rim upon different types of Wheels.

2. demountable rim provided upon the inner periphery thereof` with three annular ribs, tivo of the ribs beingn located one side of the rim and beine each provided with a bearing snritace. While the third rib is located toward the other side of 'the rim and is provided with two bearing suraces different selected combinations of the bearing' sur-faces being adapted to be need in sea-ting the rini upon different types of ribs is located toward 'the oppo of the and provided with a pair ot reversely inclined beveled nea ing snrisces,
